UNITED STATES PETER J. BOLAND, OF BERWYN, PENNSYLVANIA. I

DANGER SIGNAL.

Application filed July 24, 1922. Serial Nb. 577,177.

To all whom it may 0on0er7t:

Be it known that I, PETER J. BOLAND, a citizen of the United States,residing at Berwyn, in the county of Chester and State of Pennsylvania,have invented new and useful Improvements in Danger Signals, of whichthe following is a specification.

This invention relates to signal devices and has for its object theprovision of an illuminated sign or signal device designed for use onhighways to be located at cross roads, turns and similar points wheredriving is dangerous whereby to warn motorists and others that theyshould slow down, watch out for sharp curves and the like, the devicehaving the great advantage of operating as a preventive of accidents.

An important object is the provision of a sign of this character whichmay be formed of any suitable number of panels which are adjustablymounted so that the device may be particularly adapted for use at curvesof varying sharpness, forks or cross roads, the V adjustment of theanels permitting them to be visible from different angles. Anotherobject is the provision of a. device of this character which containsilluminating means whereby it may be seen equally well by night as byday.

Another object is the provision of a device of this character in whichthe panels are not only adjustable in regard to their angularinclination with respect to one another but which is also provided withmeans for tilting the panels in case the device is located in adepression or hollow or upon a bank.

An additional object is the provision of a signal device of thischaracter which will be simple and inexpensive in manufacture, easy toinstall and adjust, positive inaction, efficient and durable in serviceand a general improvement in the art.

With the above and other objects and advantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings inwhich:

Figure 1 is a front elevation of a construction embodying my invention.

Figure 2 is a plan view.

Figure 3 is a rear elevation of one of the panels.

Figure 4 is a vertical section on line H of Fig. 3. i

l1Figure 5 is a plan view of the base plate form a firm base for thesignal device. Suit- Figure 6 is a view of a road showing the to thedraw- 1 ably secured upon the upper end of this post is a base plate 11having a socket port1on 12 fitting on the post. This base plate carriesa plurahty of upstanding pivot pins 13 and is formed with acorresponding number of arcuate slots 14 concentric with the plns. Y

The device further includes a plurality of rectangular box like casings15 formed preferably of sheet metal and provided on their open frontsides with glass panes" 16 bearing whatever warning legend is desired.Anysuitable illuminating means, such as an incandescent bulb 17, isprovided within each casing 15 and located within the casing is somesort of reflector 18. i The manner of supplying current to theincandescent lamp is a mere detail not described and not shown as beingof no consequence.

The mounting for each signal casing 15 comprises an L-shaped bracket 19and these brackets are formed with holes 20 which are engaged upon thepivot pins 13. Each bracket carries a bolt 21 passing therethrough andengaging within slot lei-for v permitting swinging adjustment of thebrackets, and these bolts carry nuts 22. The upper ends of the bracketsare formed as sockets 23 within which are engaged one end ofcurved leafsprings 24 which have their other ends secured in sockets 25 which aresecured to the backs of the casings 15. Carried by each spring where itis secured to the casing is a threaded rod 26 which passes through ahole in the associated bracket 19 and which carries adjusting nuts 27which may be turned for the purpose of tilting the casings 15 up ordown.

Mounted at the upper corners of the casings 15 are brackets 29 havingslotted ends 28 to which are secured signs 30 which are inscribed withlegends corresponding to therein, a fork and also a cross road. It

is intended that my device be used at these varlous points as lndicatedon this view and it Will be apparent that at curves it is necesatcrossroads four will be necessary."

gardless of where the devlce 18 used 1t 1s saryto use only two of thesign members 15 while at a fork three would be used and obvious that thevarious sign members 15 may be adjusted-upon the base plate 11 bymeansof'the pivotal'mounting of the brackets 19 and the slot and boltmeans for efiecting adjustment. By turning the nuts27 it is apparentthat the sign members 15 may be tilted downwardly and forwardly orupwardly and rearwardly depending upon whether the device bemounted on abank or in a hollow, the object being to bring the sign members in suchposition as to insure their being seen by travelers using the road.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a simply .con-

str'uctedland' consequently inexpensive warning Signor signal devicewlnch 15 well adapted for highway use and which will operate as a "greatsafety appliance in preventingaccidents by warning and instructmgmotorlsts'and' others in regard to dangerous curves and other conditionsnecessitating caution.

While I have shown and described the preferredembodiment of the.invention it is of course to be understood that I reserve the righttomake such changes in the form, construction and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

Having thus describedv my invention I claim; i

1 A device of the character described comprising in combination a baseplate, a I

sign supporting member .pivotally supported onsaid base plate so asto beangularly" ad justable thereon in a horizontal plane,

2'. A device of the character described comprising a support, a baseplate mounted thereon, a plurality of brackets rotatably ad justabiymounted upon the base-plate, and 'a plurality of tiltably mounted signmembers carried bysai'd brackets, each sign member including a casingcontaining illuminating means and covered by a glass panel bearingwarning legends.

'3. A sign device of-the character described comprising a support, abase plate carried thereby-and provided with arouate slots, upstandingbrackets pivoted; upon said base plate and carrying clamping boltspassing through the slots for providing rotatable ad justmen't of thebrackets and sign members carried by the brackets, the mounting for thesign members consisting of U-shaped leaf springs secured atone end tothe sign members and having their other ends secured to the associatedbrackets.

at. A sign device of. the character described comprising a support, abase plate carriedthereby and provided with arcuate slots, up-

standing brackets pivoted upon said base plate and carrying clampingbolts passing through the slots for permitting rotatable ad ustment ofthe brackets, and sign niem-- bers carried by the brackets, the mountingfor the sign members consisting of U-shaped leaf springs secured at oneend to the sign members and having their other ends secured to theassociated brackets, and threaded rods carriedby the sign members,passing through holes in the associated brackets-and carrying adjustingnuts whereby to effect tilting of the sign members.

In testimonywhereof I aiiiX my signature.
